<p>Most APIs that refer to an <code class="literal">index</code> parameter support execution across multiple indices,
using simple <code class="literal">test1,test2,test3</code> notation (or <code class="literal">_all</code> for all indices). It also
supports wildcards, for example: <code class="literal">test*</code> or <code class="literal">*test</code> or <code class="literal">te*t</code> or <code class="literal">*test*</code>, and the
ability to "exclude" (<code class="literal">-</code>), for example: <code class="literal">test*,-test3</code>.</p>
<p>All multi index APIs support the following url query string parameters:</p>
<div class="variablelist">
<dl class="variablelist">
<dt>
<span class="term">
<code class="literal">ignore_unavailable</code>
</span>
</dt>
<dd>
(Optional, boolean) If <code class="literal">true</code>, missing or closed indices are not included in the
response. Defaults to <code class="literal">false</code>.
</dd>
<dt>
<span class="term">
<code class="literal">allow_no_indices</code>
</span>
</dt>
<dd>
<p>
(Optional, boolean) If <code class="literal">true</code>,
the request does <span class="strong strong"><strong>not</strong></span> return an error
if a wildcard expression
or <code class="literal">_all</code> value retrieves only missing or closed indices.
</p>
<p>This parameter also applies to <a class="xref" href="indices-aliases.html" title="Update index alias API">index aliases</a>
that point to a missing or closed index.</p>
</dd>
<dt>
<span class="term">
<code class="literal">expand_wildcards</code>
</span>
</dt>
<dd>
<p>(Optional, string) Controls what kind of indices that wildcard expressions can
expand to. Multiple values are accepted when separated by a comma, as in
<code class="literal">open,hidden</code>. Valid values are:</p>
<div class="variablelist">
<dl class="variablelist">
<dt>
<span class="term">
<code class="literal">all</code>
</span>
</dt>
<dd>
Expand to open and closed indices, including <a class="xref" href="index-modules.html#index-hidden">hidden indices</a>.
</dd>
<dt>
<span class="term">
<code class="literal">open</code>
</span>
</dt>
<dd>
Expand only to open indices.
</dd>
<dt>
<span class="term">
<code class="literal">closed</code>
</span>
</dt>
<dd>
Expand only to closed indices.
</dd>
<dt>
<span class="term">
<code class="literal">hidden</code>
</span>
</dt>
<dd>
Expansion of wildcards will include <a class="xref" href="index-modules.html#index-hidden">hidden indices</a>.
Must be combined with <code class="literal">open</code>, <code class="literal">closed</code>, or both.
</dd>
<dt>
<span class="term">
<code class="literal">none</code>
</span>
</dt>
<dd>
Wildcard expressions are not accepted.
</dd>
</dl>
</div>
</dd>
</dl>
</div>
<p>The defaults settings for the above parameters depend on the API being used.</p>
<p>Some multi index APIs also support the following url query string parameter:</p>
<div class="variablelist">
<dl class="variablelist">
<dt>
<span class="term">
<code class="literal">ignore_throttled</code>
</span>
</dt>
<dd>
(Optional, boolean) If <code class="literal">true</code>, concrete, expanded or aliased indices are
ignored when throttled.
</dd>
</dl>
